Ambiviricota is a phylum of ambisense, single-stranded RNA viruses that infect fungi.

These RNA virus genomes contain at least two open reading frames in a non-overlapping ambisense orientation.

The ambisense structure allows the virus to encode two proteins on opposite strands of RNA.

[1] Ambiviruses have been found to infect various species of fungi, making them an important area of study for understanding viral interactions within these hosts.

[1] The name Ambiviricota is derived from the Latin word "ambi", meaning "both", referring to the non-overlapping ambisense orientation of the open reading frames in its taxon members' genomes.
